No. that's not what I was proposing.  My suggestion was to use these
routines if they are sufficiently widely implemented, and our own
routines where standard ones are not available.

The man page for mblen says
"CONFORMING TO
       ISO/ANSI C, UNIX98"

Is glibc really the only C library to conform?

If using the mb... routines isn't feasible, IBM's ICU library
(http://oss.software.ibm.com/icu/) is available under the X licence,
which is compatible with BSD as far as I can see.  Besides character
conversion, ICU can also do collation in various locales and encodings.
My point is, we shouldn't be writing a new set of routines to do half a
job if there are already libraries available to do all of it.
